Abstract
A new approach toward development of nanosize materials based on water-soluble polymers is suggested. Nanosize aluminum-containing structures screened by a polymer sodium carboxymethyl cellulose shell are obtained at temperatures of 70–80°C by introducing Al microparticles with a size of up to 10 μm into an aqueous solution of sodium carboxymethyl cellulose. The methods of XRD and IR spectroscopy were used to establish that metallic aluminum is present in nanoparticles and the polymer Na CMC matrix is preserved without fundamental changes. Electron microscopy is used to characterize the morphological regularities and elemental composition of nanoparticles. Agglomerates of the obtained particles reach a size of about 300–500 nm and consist of tubular structures with a size of up to 150 nm with a total thickness of 3–5 nm. This approach may form the basis for a comparatively simple and cheap method of obtaining nanosize particles that can serve as modifying agents in protective corrosion-resistant coatings.
